    • There is disclosed a baby walker to be used by a child wherein the body of the child is supported above the ground so that the feet of the child are in contact with the ground, thus permitting the child to propel the baby walker. The baby walker comprises means for permitting the walker to be collapsed or expanded, and means for locking said collapsing and expanding means to fix top and bottom members of the baby walker in a desired one of several positions. In this manner, the seat supporting the child is adjustable so that the distance to the ground may be controlled for different sized children, or for the same child over a period of growth.
    • 公开了一种儿童使用的婴儿步行者,其中儿童的身体被支撑在地面之上,使得孩子的脚与地面接触,从而允许儿童推动婴儿步行者。 婴儿步行者包括用于允许步行者塌陷或膨胀的装置,以及用于锁定所述塌缩和扩张装置以将婴儿助行器的顶部和底部构件固定在多个位置中期望的一个位置的装置。 以这种方式,支撑孩子的座椅是可调节的,使得距离地面的距离可以针对不同大小的孩子或对于相同的孩子在一段时间的增长中进行控制。
